ACTIVITY
(Setting range 0 – 36) The velocity at which the servo moves the
control surface. The higher the number the more movement you will
see in the control surface. With a standard servo (DSB-X, DSP-X)
you should start at 0 then work your way up in flight to set the level
for your aircraft. The High Torque Servo (DSB-HB, DSB-HC) has a
different gear ratio, so an Activity setting of 12 will be equal to about
0. With too low a setting the aircraft will hunt slowly and appear to be
lazy. With too high a setting the aircraft will hunt rapidly, and appear
nervous and jittery.
MICRO
(Setting Range 0-31) This is used to remove the significant lost motion in the control system, usually a
cable control system. Most aircraft do not need this changed from 0. An example of when one might
need to adjust microactivity is if flying in still air, there is a very slight wing rock that cannot be solved by
adjusting the ACTIVITY setting.
ROLL
(Setting Range 0-4) Most aircraft do not need this changed from 0.
Only aircraft type like CT & CUB that have adverse Yaw with turns
(rudder assist). We recommend factory assistance before adjusting this
value.
BANK
(Setting Range Low – MED – High) This setting limits the maximum
bank angle of the aircraft to approximately 13 degrees at the low
setting, 18 degrees at the medium setting, and 24 degrees at the high
setting.
STATIC
(Setting Range Low – MED – High) This setting is used to
compensate for lag in the aircraft static system. This setting is usually
not adjusted. This value is used to remove very slow hunting, of more
than 15 to 30 feet, in altitude hold when adjusting the activity setting
does not solve the problem. This is NOT the setting to adjust if there is slight nose bobble in still air; the
setting for that situation is HALF STEP. We recommend factory assistance before adjusting this value.
